. the door.

To all whom it may concern:

Be it known that I, ALEXANDER MCPHER;

SON, a British subject, residing at New Grlasgow, in the county of Pictou, in the Province of Nova Scotia, in the Dominion of Canada, have invented new and useful Improvements in Door-Hangers, of which the following is a specification.

My invention relates to hangers to which rolling doors are attached at the top, but is equally applicable for attachment at the bottom, and the objects of my invention are to provide an inexpensive hanger, one not liable to get out of order and having the minimum amount of friction in its operation. I attain these objects by the mechanism illustrated in the accompanying drawing, in which,

Figure l is a front view of my invention;--Fig. 2 is a section on line (Z) c) of Fig. 1.

Similar letters refer to similar throughout the several views.

A is the hanger iron to which the door is secured and which contains the door moving mechanism.

B is a channeliron, which is secured to the car or building to which the door is to be connected. The inner faces of the flanges 0f the channel iron preferably diverge outward and on the inner face of the lower flange is located a substantially half round track iron d. (a) is a grooved metal wheel, the outer side of which may be of slightly greater diameter than the inner side thereof. Said Wheel rolls on said track iron and is spaced between said track and the under side of theupper flange of said channel, leaving a slight clearing space atthe top, which arrangement not only prevents the wheel from leaving the track, but effectually obviates any possibility of the wheel binding when one end of the door is tilted up, as when the wheel is raised from the track. while it is moving, it will simply roll, on

parts the under side of the upper channel flange.

I (b) is the axle, carrying said wheel and can an integral'part thereof, or to the same by any eflicient means. (0. 0. 0.) are antifriction rollers, carried within the hub of said hanger iron and surrounding said axle on which it revolves, thus insuring the minimum amount of friction, during the operation of moving be formed as Copies of this patent may be obtained 'for live cents each, by addressing the Specification of Letters lPatent.

Patented net. 12, 1915.

(f) is a collar on the outer end of the axle, secured thereto by the pin (6) and by overlapping the rollers (a), which are located said wheel and the collar tainsall the moving mechanism in its proper position.

If desirable antifriction balls may be substituted in lieu of rollers without impairing the efficiency of the invention.

Having described and illustrated my invention, what I claim and desire to secure by patent is: I

1. In a door hanger,

a. horizontally disposed channel iron whose flanges extend outward, a'strip of substantially semi-circular formation in cross section secured in rigid relation to the upper face of the lowermost flange to form a track, a hanger iron whose upper end is formed to provide a relatively long bearing extending transversely of the hanger iron beyond the frontand rear faces of the same, track, an axle for the wheel whose outer end projects beyond the outer end of said bearing, anti-friction rollers disposed between the bearing and the axle, the anti-friction rollers being of substantially the same length as the bearing, a collar detachably secured to the projecting outer end of the axle and engaging the outer end of the bear ing to confine said rollers within the beara grooved wheel to roll on said.

parallel with said axle between v iteffectually reing and to hold said wheel against lateral displacement with relation to the inner end of the bearing.

2. In a door hanger, a horizontally disposed channel iron whose flanges extend outward and the inner faces of which diverge outward, a strip of substantially semi-cir-' cular formation incross section secured to the upper face of the lowermost flange to form a track, a hanger iron whose upper end i is formed to provide a bearing, a grooved wheel to roll on said track, the outer side of the wheel being of slightly greater diameter than the inner side thereof, an axle for the wheel mounted in said bearing, anti-s Washington, D.
